The article develops the concept of the "sensible port" as a model of responsibility and business prudence in port operations. It highlights the importance of the duty of precaution to ensure continuity, efficiency, and safety, while preventing incidents and protecting the economy, the environment, and the port community.
“The figure of the sensible port.” It is an ideal, a standard, the embodiment of all the qualities we demand of a good entrepreneur (…) “The reasonable port is always thinking about the success of its clients; prudence is its guide, and fulfilling its duty of ‘precaution’ comes first—it is the rule of its business. The port plans years in advance for its direction and carefully examines the terrain before expanding its capacity; it does not dawdle or get lost in contemplation when approaching the traps created by emerging hazards at the edge of its dock; it always records in the digital footprints of its operations as many details as appropriate; it never stores hazardous cargo for longer than prudent; it does not allow a vessel to berth unless it is seaworthy; it thoroughly investigates the good faith of each shipping company and cargo generator before agreeing to provide services, and it informs itself of the history and professional habits of its port service providers before contracting them; it does not believe in or repeat tavern gossip unless it has a solid basis to believe it true; it never acts prematurely before those ahead have fully vacated the hole that is its own target; it never asks too much from its shareholders, competitors, stevedores, or gantry cranes; in its business, it only seeks a modest profit that a small group of colleagues considers ‘fair,’ and regards its fellow merchants, agents, and goods with the degree of suspicion and caution that the law deems admirable; it never curses, gambles, or loses control; it always behaves with moderation, and even when disciplining its child, it considers the middle ground. It stands as a monument in our courts, calling in vain on its fellow citizens to order their lives according to its example […].”[1]
The services carried out at a port terminal are of “public interest” and must be provided in an “uninterrupted, continuous, and efficient” manner[2], under conditions of “safety”[3], fulfilling the “duty of precaution” in the conduct of a “specialized” business, since the work performed constitutes a “Hazardous Activity”[4].

Maintaining the continuity, efficiency, and safety of port operations ensures the constant flow of goods, helping to sustain a nation’s competitiveness, economy, trade, and efficient logistics. Continuous port operations are essential for the security and efficiency of the supply network, as well as for product price stability and food security. [6]
Any disruption of port activity[7] caused by an incident within port facilities, in access channels to the dock, or related to political and natural risks triggers a chain of negative effects that impact the industry and the economy at large. Therefore, it is an issue of concern not only for port operators but also for governments, businesses, and society as a whole.
The users of the services provided by ports and their operators include shipping companies, importers and exporters, freight forwarders, land carriers, logistics operators, customs authorities, and other service companies. The services provided within a port are numerous, generate risks and hazards, and include the following:
Table 1. Some Types of Port Services Provided at a Terminal [8]

The purpose of this article is not to explain the civil liability regime applicable when the plaintiff/victim (shipowner, shipper, exporter, importer, third parties, etc.) suffers harm caused by the defendant/perpetrator (port, port operator) due to their action, omission, or breach of an obligation in the direct execution of a port service. What we aim to convey is the importance for a port terminal to incorporate into its technical conditions regulations[9] and port expansion plans[10] the concept of the duty of “Precaution” as a best practice to prevent port operations from experiencing disruptions that impact the economy and the port community[11].
The duty of “precaution” that the port and its operators must observe can be defined as the professional and moral obligation of an entrepreneur in a specialized industry to act with due diligence, discretion, and caution in order to avoid or prevent inconveniences, difficulties, or damages that may arise.[12]
Grafica II.[13]
<In Graph II, we denote precaution by the continuous variable x, so that larger values of x correspond to higher levels of precaution. Generally, the plaintiff (exporter, importer of goods, shipowner, freight forwarder, etc.) in a negligence lawsuit must demonstrate that the defendant (port, port operator) breached an obligation owed to the plaintiff. A duty to act with care is a legal standard prescribing the minimum acceptable level of “precaution.” In Graph II, ~x denotes the legal standard. Precaution below ~x violates the duty of care, while precaution equal to or above ~x satisfies the duty of care. The “precaution” level ~x divides the graph into two zones: a permitted zone and a prohibited zone. Therefore, x < ~x implies that the actor is at fault, while [x ≥ ~x] implies that the actor is not at fault, where x indicates the actual amount of precaution taken by the defendant/perpetrator. Port activities are constantly evolving, transforming and generating additional port risks (automation of equipment, digitization of processes, sustainability, increased vessel capacity, congestion, etc.), requiring the implementation of measures to prevent incidents and avoid congestion[14], with the primary objective of maintaining continuity in service delivery. Examples of such measures include:
Implementing a “Precaution” strategy not only protects people and the environment, but also contributes to the sustainability, economic viability, and efficiency of port operations, as follows:
